Sony Corporation is one of Japan’s biggest multinational conglomerates. It isrenowned worldwide for high-tech innovation and quality electronics products, many of which are household names. It was founded by Akio Morita and Masaru Ibuka in 1946. They popularized tiny transistor radios and gained a solid market share in Europe and the U.S. The Sony name was created by combining "sonus," (Latin for "SONIC," meaning sound), with "sonny," - a youthful boy. It was chosen for its simple pronunciation that is the same in any language. Today, Sony is a market leader in batteries, computer game consoles, cameras, music and movies and financial services. The Sony Walkman and PlayStation are among their pioneering products. The company’s turnover is close to $100 billion a year.
